Definitions

• the invention relates to dual purpose antiseptic fluids, which additionally to being effective skin disinfectants are also capable on drying to form skin protective film with residual antibacterial properties.
• antiseptic fluids while primarily applied as skin disinfectants for pre- and post surgery, dermatological infections, burn treatment as well as first aid for superficial wounds, cuts and abrasions, offer the additional advantage of a temporary or longer lasting skin and wound dressing depending on the film forming polymer used, without impairing the normal physiological activity of the skin.
• the invention also relates to medical, surgical and veterinary devices in particular to liquid applicators for antiseptic fluids to the human skin for medical, pre-and post surgical applications and first-aid
• Antiseptic fluids are solutions of a substance of known antibacterial properties dissolved in a solvent such as water or a lower alcohol or mixture of both.
• the bactericidal substance is, after application, deposited directly onto the skin and can through its contact cause to persons known to have hypersensitive skin, or to be allergic, considerable discomfort through reddening, itching or other sensations.
• plastic bandages are usually solutions of an acrylic or methacrylic co-polymer dissolved in a volatile non-aqueous organic solvent of low boiling point such as ethyl acetate, acetone, ethyl alcohol or methylene chloride or mixtures thereof, reducing drying time to a minimum.
• liquid bandages Although they protect the treated areas through their coherent film formation acting as a physical barrier against outside contamination and possible infection, they have no antibacterial activity and should therefore only be applied after disinfection of the skin.
• a serious disadvantage of these liquid bandages is that the non-aqueous solvent for the film forming polymer can cause considerable pain if applied to open wounds, cuts and abrasions. For good adherence, such liquid bandages can only be applied to perfectly dry skin. This makes them less suitable where the skin is contaminated by body fluids such as blood, strong perspiration or pus.
• these liquid bandages suffer from the disadvantage that the film consisting of a non-porous water-insoluble polymer closes the pores of the skin hermetically, thus not allowing it to perform its normal physiological functions. Modifications of such films have been claimed to make them semi-permable to be better able to cope with the body fluids exuded from the skin.
• More recently spray plastic bandages have been described, whereby the polymer is dissolved in an organic solvent or the propellant itself to form a film on the skin removable by washing with soap and water.
• a spray bandage is also described in Australian Patent No. 527 826 where the film consisting of a water insoluble polymer such as polybutylmethacrylate is dissolved in an organic solvent containing a water soluble bactericide such as a quaternary ammonium compound and bacteriostat such as a chlorinated hydroxydiphenylether.
• the water soluble bactericide will be leached out from the polymeric film for the immediate disinfection of the skin and that the resulting porous film will subsequently allow sufficient humidity to pass through, for the remaining bacteriostat in its anhydrous medium to exert residual antibacterial activity.
• antiseptic preparations being aqueous solutions of an iodine complex with ⁇ oly(N-vinyl-2-pyrrolidinone), which after application leaves a film ⁇ f. the iodine complex on the skin.
• This film formation is only incidental to the disinfecting properties and because of the thinness of the film as it is removed immediately when in contact with moisture, it cannot be regarded as a protective wound dressing.
• the antiseptic fluid is held in an open container and the swab dipped into its content, which is discarded after the operation, causing a waste of the larger part which remained unused. Furthermore, the swabs or sponges discarded after use could easily be mistakenly included in the swab count if contaminated with clotted blood or after use with an iodine disinfectant because of similarity of colour.
• An improvement in the art is disclosed in US Patent No.
• the present invention thus relates to a dual purpose antiseptic fluid which additionally to being a liquid disinfectant for broken and unbroken skin, open wounds, burns, cuts and abrasions, leaves a protective dressing in form of an elastic film over the treated areas with residual antibacterial properties.
• the dual purpose antiseptic fluid of the invention after disinfection provides an elastic dressing which does not interfere with the normal physiological activity of the skin and is removable with water or with soap and water.
• the antiseptic fluid of the invention causes a minimum or irritancy to sensitive skin otherwise caused by the direct contact and deposition of the bactericide and/or bacteristat direct onto the skin.
• the invention also relates to a simple, reusable device for the application of the antiseptic fluid in an economic and effective manner to surfaces such as skin.
• the invention therefore provides a dual-purpose antiseptic fluid comprising at least one bactericide and/or bacteristat at least one water-soluble or water-dispersable film forming polymer and water.
• the fluid of the invention may optionally contain a water miscible, non-toxic volatile co-solvent such as a lower alcohol, e.g. ethanol. isopropanol, or the like.
• a water miscible, non-toxic volatile co-solvent such as a lower alcohol, e.g. ethanol. isopropanol, or the like.
• the use of a slow drying solvent in such antiseptic fluids allows sufficient time for the active ingredients to act as in any other antiseptic fluid to assure complete disinfection of the treated skin area. It is generally accepted that for efficient skin disinfection, the composition should be in contact with the skin for about 30 to about 90 seconds. For practical purposes however, the drying time of the solvent should be adjusted by the addition of the appropriate quantity of a water miscible volatile co-solvent such as ethanol or isopropanol, so that film forming takes place preferably between about 30 and about 60 seconds. It is also preferred that the concentration of the active ingredient is sufficient to achieve complete disinfection of the skin during film formation.
• co-solvent content might be raised as high as 70% by volume to reduce drying time to a few seconds only.
• additional bactericidal power of co-solvents such as ethanol at this concentration assures asepsis of the skin even within the reduced drying time.
• a distinct advantage of the dual purpose antiseptic fluid of the invention containing a water-retaining film forming polymer is that after disinfection of the skin, not only residual antibacterial activity is maintained, but that it is directed simultaneously against the outside environment and the skin. Thus, even if a slow acting bacteristat is employed, disinfection of the skin is continued even if the film has been formed before asepsis of the skin has been achieved. There is also the important added advantage that after normal disinfection of the skin the remaining bacterial flora residing in the depth of the skin tissue, often protected by fatty matter, and brought to the surface at a later time by perspiration, is destroyed on contact with the active ingredient in the film.
• quaternary ammonium compounds can reasonably be understood, as, on dissolving the film forming polymer, a protective colloid is formed around the molecule of the bactericide, and which without interfering with its antibacterial activity is preventing its direct contact with the skin not only during disinfection but even more so once film forming has set in.
• Another advantage of the protective colloid and the film formation around the molcule of the bactericide is that the possible deactivation through organic matter is reduced and residual antibacterial activity is increased.
• the use of a water soluble polymer has the further advantage that by selecting, polymers of sufficient high molecular weight, the viscosity of the antiseptic fluid can be adjusted to be sufficiently high as to avoid unnecessary and annoying run-off after application.
• plasticisers are for example the polyethylene glycols or a surface active substance such as the nonylphenolpolyethoxy condensates to assure even spreading of the antiseptic fluid on the skin prior to filmformation in emergencies on unwashed skin and those people whose skin is oily or fatty.
• the fluids of the invention optionally may contain a moisturiser. This is especially useful to enhance the moisture retaining properties of the polymeric film. Some moisturises may additionally act as a plasticiser. Examples of suitable moisturisers include glycerol, sorbitol, diethylene glycol. polyethylene glycol 400 and nonionic lanolin derivatives. Suitable bactericides and bacterisetats which may be employed in compositions of the invention include halogenated hydroxydiphenyl derivatives or halogenated salicyl and carbanilides.
• bactericides and/or bacteristats are those of the formula
• each of R 1 to R 9 may be hydrogen, halogen, lower alkyl, haloloweralkyl, lower alkoxy, allyl, cyano, amino or acetyl and the O-acyl derivatives thereof provided that at least one of R 1 to R 9 is halogen:
• each of X 1 to X 10 may be hydrogen, halogen, haloalkyl, nitro or alkoxy provided that at least one of X 1 to X 9 is halogen:
• each of Y 1 to Y 9 is hydrogen or halogen, provided that at least two of Y 1 to Y 9 are halogen;
• each of Z, to Z 8 may be hydrogen or halogen provided that there is at least two halogen substituents on each Phehyl ring.
• Examples of the preferred bactericides and/or bacteristats include 2,4,4'-trichloro-2'-hydroxydiphenyl ether (triclosan); 2,2'-dihydroxy-3,3',5,5' 6,6'- hexachlorodiphenylmethane systematic name (hexachlorophene); 3,5,4'-tribromosalicylanilide (tribromsalan), 3,4,4'-trichloro- or 3-trifluoromethyl-4,4'-dichlorocarbanilides (triclocarban and cloflucarban), chlorhexidine digluconate, cetyl trimethylammonium bromide, benzalkonium chloride and iodine complexes known as iodophors.
• triclosan 2,4,4'-trichloro-2'-hydroxydiphenyl ether
• the concentration of the active ingredient should be within the range recommended by the manufacturers, and be no different to those used in standard antiseptic solutions.
• the film forming polymers, which provide films with sufficient water retention to allow for bactericidal bacteristatic activity of the incorporated active ingredients are, for example, methylcellulose, ethylcellulose.
• Suitable polymers are for example co-polymers of vinyl acetate and crotonic acid, ter-polymers of N-vinyl-2-pyrrolidinone with vinyl acetate and alkylaminoacrylates or methacrylates.
• Suitable polymers are also methylcellulose, ethylhydroxycellulose or hydroxymethylcellulose or ethylcellulose.
• a suitable grade used in conjunction with a povidone-iodine or a povidone-iodine copolymer, they have the added advantage that viscous, non-running fluids are obtained allowing an even covering of well defined areas of the skin, resulting in a longer lasting antiseptic protective film against post-operative infections, with higher resistance against abrasions when applied under plaster casts and bandages than was hitherto possible to obtain.
• N-vinyl-2-pyrrolidinone is a co-monomer
• the co-polymer can be directly complexed with iodine using the poly(N-vinyl-2-pyrrolidinone) component to serve as the iodine carrier.
• the water soluble alkali metal salts of carboxymethylcellulose can be used in conjunction with other polymeric film forming substances at a pH preferably between 7.0 and 8.0, but not much below pH 6.0. Due to their ionic character care has to be taken in the choice of the bactericides being part of the composition as to their compatibility. Thus they cannot be used in conjunction with cationic substances such as quaternary ammonium compounds.
• Suitable examples of substances for partial salt formation of these polymers to render them more hydrophilic or even completely watersoluble are: 2-aminomethylpropanol, diethylaminopropylamine and tri-isopropanolamine.
• the dual purpose antiseptic fluids according to this invention are suitably applied by any conventional method such as painting, swabbing or dabbing onto the skin or by means of a suitable applicator.
• the invention provides apparatus for applying a fluid to a surface, which apparatus comprises a container for said fluid defining a reservoir, an applicator head in fluid communication therewith, fluid flow restricting means between said reservoir and said applicator head, first cap means associated with said container for filling with fluid and second cap means for said applicator head to prevent evaporation of fluid therefrom, wherein said applicator head comprises a resilient porous pad held in a dome shaped cap in content with said fluid flow restricting means.

• the perforation of the cap (5) is such that the pad (6) is evenly moistened, preferably by a number of small symmetrically placed holes.
• the size of the perforations depending on the viscosity of the fulid is to be such that by inverting the applicator (1) no gravity feed into the pad occurs and a small amount of pressure on the reservoir (2) is needed for the necessary amount of fluid to moisten it.
• the applicator when not in use, is hermetically closed by a removable outer cap (3) which either screws or clips on, made of a similar material as the perforated dome-shaped cap (5). This assures that any vapours from the antiseptic fluid cannot escape, thus keeping the pad (6) continuously moist. This assures the the device not only being protected from outside contamination but being always ready for use since no drying of the surface can occur.
• the reservoir (2) is suitably made from a resilient semi-rigid material such as high density polyethylene or propylene, enabling the antiseptic fluid to flow when inverted into the pad (6) on applying pressure to the side walls.
